        This function is used to write data to the stream file. The function
        call will block until one or more bytes of the data has been written
        successfully, or until an error occurs.

        The write_some operation may not transmit all of the data to the peer.
        Consider using the <a class="link" href="../../write.html" title="write"><code class="computeroutput"><span
            class="identifier">write</span></code></a> function if you need to
        ensure that all data is written before the blocking operation completes.
